SIIHON-TUBE BASE.

Application filed May 2'7, 1921.

Too whom it may concern:

Be it known that 1, Honor KLEIN, a citi- Zen of the United States, and aresident of taken through the base on the line 3-S of Montclair, in thecounty of Essex and State of New Jersey, have invented new and usefulImprovements in Siphon-Tube Bases, of which the following is aspecification.

This invention relates in general to tubes or pipes utilized for drawingliquid from a container having sediment or foreign matter at the bottomthereof, and more particularly to a base or terminal for such tubes orpipes to prevent the said sediment or solid matter from entering thetube or pipe and enabling only clear liquid to enter the same Theobjects of the invention are to provide a base or terminal of thecharacter described embodying novel features of construction wherebyclear liquid may be drawn from the extreme bottom of a con'- tainercontaining sediment or foreign matter; toprovide a cup-shaped memberhaving a rigid upstanding projection on its bottom within the rim toreceive the end of an elastic tube or pipe,'said projection being formedto permit passage of liquid from the interior of said cup-shaped memberinto said tube or pipe, the sides of said member excluding foreignmatter from the interior thereof; to provide an improved constructionfor said projection to receive the end of a tube or the like wherebyample clearance between said tube and said projection for the passage ofliquid is provided; to provide in such a device means for limiting themovement of the tube or pipe onto said projection and maintain the endof said tube or pipe in spaced relation to the bottom of said cup-shapedmember to permit passage of liquid from withinthe said member into saidtube; and to obtain other results and advantages as may be brought outby the following description.

Referring to the accompanying drawings, in which like numerals ofreference indicate the same parts throughout the several views,

view through the base taken on the line 22 of Fig. 4;

Figure 3 is a transverse sectional view Fig. 4;

Figure 4 is a top plan View of the base;

Figure 5 is a horizontal sectional view through the projection of thebase for receiving the end of the tube or pipe, taken on the line 55 ofFig. 3.

For the purpose of illustrating the uses of my invention I have shownthe base or terminal A connected to the end of a flexible tube B andutilized for withdrawing clear liquid from a container G, such as acrock, which has sediment or foreign matter D at the bottom thereof.

The base A is substantially circular and comprises a disk-like bodyportion 1 provided with an upstanding annular wall 2 on one sidethereof, the body portion 1 be ing adapted to rest upon the bottom ofthe container with the annular wall 2 projecting upwardly through thesediment in the container to a point above the surface of the sedimentas shown in Figures 1 and 2. The base A is thus substantially cupshapedand is preferably formed of a heavy material which will cause the baseto sink by gravity to the bottom of a container. Arranged substantiallyaxially of the body 1 and within the annular upstanding wall 2 is aprojection 3 which serves to connect the base A to the end of a tube,pipe, or the like. In the present in stance I have shown the base A usedin connection with a flexible tube 13, and the tube is connected to thebase by telescopically forcing the end of the tube over the projection8, as shown in Figures 2 and 3, the tube being held in position byfriction. In Figures 2, 3, 4 and 5 the projection 3 shown assubstantially rectangular in crosssection and formed with, longitudinalgrooves at in opposite sides thereof which extend the full length of theprojection, and merge into the body portion 1 of the base within theannular upstanding wall 2. These grooves t thus provide clearancebetween the projection 3 and the walls of the tube B, as clearly shownin Figures 2 and 5, so that the liquid in the container C can pass intothe end of the tube B as indicated y t e arrows. For the purpose of proventing the end of the tube B from being slipped over the projection 3into engagement with the body portion 1 of the base so as to preventliquid from entering the tube, the projection 3 is provided at a pointintermediate its length with shoulders 5 which are engaged by the end ofthe tube as it is slipped over the projection 3.

Vvith this construction it will be seen that the upstanding annular wall2 of the base will prevent the sediment or foreign matter D fromentering .within the annular wall and passing into the tube B, and atthe same time the end of the tube is positioned in close proximity tothe bottom of the container and even below the surface of the sediment.The clear liquid can thus flow over the top of the wall 2 and thendownwardly below the end of the tube B and up ardly through the grooves1 in the projection 8 out of the container to a desirable point.

A base constructed in accordance with my invention is particularlyadaptable for use with flexible and elastic siphon tubes, such as arubber tube, the base being constructed to rest by action of gravityupon the bottom of the container and penetrating the sediment thereinwhereby clear liquid may be withdrawn from the extreme bottom of thecontainer and the sediment of foreign matter completely excluded fromthe siphon tube. The rigid projection 3 enables an elastic tube to beeasily and quickly slipped over it and the base 1 is held on the tube bythe elasticity and frictional engagement of the tube with saidprojection, whereby the base can be quickly attached to and removed froma tube and interchangeably used with a number of tubes of substantiallythe same diameter. Further, the base embodying the invention can bemolded or cast in one piece in one operation and without the use ofundercuts or special cores, so that the cost of manufacture is small.There are no cracks or corners in the device and all parts thereof areclearly accessible so that it can be easily and thoroughly rinsed andcleaned.

lVhile I have shown and described one preferred embodiment of myinvention, it will be understood that this is for the purpose ofillustrating the principles thereof only, and that many modificationsand changes can be made in the detail construction of the device withoutdeparting from the spirit or scope of the invention. The base has beenshown as used in connection with a flexible tube, but it will beunderstood that it is also adaptable for use with pipes and the likewhich are utilized for drawing clear liquid from a container, well, orthe like, having sediment in the bottom thereof. Therefore, I do notdesire to be understood as limiting myself in the construction or use ofmy invention except as required by the following claims construed in thelight of the prior art.

Having thus described the invention, what I claim is:

1. In a siphon tube, the combination of an elastic tube, and abasecomprising a cupshaped body portion having a rigid upstandingprojection on the bottom thereof, said projection being adapted totelescopically and frictionally receive said tube thereover and beingformed with passages to permit flow of liquid between itself and saidtube, said base and said tube being maintained in said connectedrelation by the elasticity and frictional engagement of said tube withsaid projection.

2. In a siphon tube, the combination of an elastic tube, and a basecomprising a cupshaped body portion having an integral solid and rigidupstanding projection on the bot tom thereof to telescopically andfriction-ally receive said tube thereover, said projection being formedwith a longitudinal interior groove to permit liquid to flow betweensaid tube and said projection, and said base and said tube beingmaintained in said connected relation by the elasticity and frictionalengagement of said tube with said projection.

3. A device of the character described comprising a cup-shaped bodyportion having a single rigid upstanding projection on the bottomthereof to telescopically receive a tube or pipe thereover, saidprojection being formed with passages merging into the bottom of saidbody portion to permit liquid to fiow from within said body portionbetween said projection and said tube into said tube.

4:. A device of the character described comprising a cup-shaped bodyportion having a single integral solid and rig d upstanding projectionon the bottom thereof to telescopically receive a tube or pipethereover, said projection being formed with an exterior longitudinalgroove merging into said bottom of the body portion to permit liquid toHow from within said body portion between said projection and said tubeinto said tube.

A device of the character described comprising a body portion havinga.continnous upstanding wall andv av solid rigid upstanding n'ojectionwithin said wall adapted to telescopically receive the end of a tube orpipe, said projection being formed with a longitudinal exterior grooveand a shoulder intermediate the ends of said groove to limit themovement of said tube onto said projection, said groove permitting thepasses of liquid from within. said wall between said projection ant.said tube or pipe into said tube or pipe.
